Question

The ocean stores carbon from its interactions with the atmosphere, so the ocean serves as (a) _________ for the carbon cycle.

Answer 1

`\boxed{Carbon~ Sink}`

Step-by-step explanation:

Any reservoir, natural or otherwise, is called a carbon sink, that accumulates or stores some carbon.

Nowadays the 2 more important carbon sinks are vegetation and the oceans.

We can also say that atmosphere, soil, and forests are the world's largest carbon sinks.

Also, we can describe the carbon sink as anything that absorbs more carbon from the atmosphere than it releases. In contrast, a carbon source is anything that releases more carbon into the atmosphere than it absorbs, e.g. the burning of fossil fuels or volcanic eruptions.
